What problem does it solve? Keeping a project roadmap document in sync with the actual state of GitHub epic issues is tedious and error-prone. This Skill owns the Epics section of docs/ROADMAP.md, adding, moving, and pruning epic entries while validating every entry against the live GitHub issue as the source of truth. ## Core Features & Use Cases - Add and move epics across horizons: Register newly filed epics into Now, Next, Later, or Recently Shipped, with title and milestone derived live from the GitHub issue via the gh CLI. - Structural validation and reformatting: On every invocation, validate all entries against a canonical format, flag DRIFT and STALE entries, and repair them only on explicit reformat trigger. - Automatic pruning: Keep Recently Shipped capped at the 10 newest closed epics, with older ones remaining discoverable via GitHub labels. - Use Case: After closing an epic issue, invoke the skill to move the entry into Recently Shipped, re-derive its milestone from the issue, and prune the section back to 10 entries in one operation. ## Quick Start Ask Claude to add epic issue 42 to the Later horizon of the roadmap, or to validate the Epics section of docs/ROADMAP.md.
